For a Chevrolet 292, what is the main bearing bore diameter in the block (without bearings installed)? And what is the tolerance for being out of round?
The measurement Iām getting using a mic and dial bore gauge is 2.4905ā straight up and down (90 degrees away from the cap parting line) But very near the parting line the bore is .0020ā larger which seems like a lot. Hoping to avoid a line bore or hone. Thanks.
